How does a zone valve work?
A zone valve is hooked directly to a thermostat. On a call for heat, the thermostat contacts close completing the circuit to the zone valve and energizing a small motor in the zone valve. This motor opens the valve.
Where do you install a zone valve on a hot water boiler?
Installation Location | Hot Water Boiler Piping Zone Valves Zone valves are typically installed on the return side of the hot water loop no matter the type of loop you have. There advantages for installing on the return side of the loop.
Which side of the loop should I install the zone valve?
There advantages for installing on the return side of the loop. One is the return side of the loop has a lower temperature, therefore, the zone valve will be subject to less heat. This likely prolong the life of the valve.
What to do if your zone valve is not working?
Zone Valve Defects Checklist. Zone valve does not work - jammed, stuck, does not open in response to call for heat at that zone. Provided the wiring and thermostat are correct and operating, if no hot water flows past the valve on a call for heat (feel the pipes for heat) it may be jammed and need replacement.
How do Z-Zone valves work?
Zone valves are connected to thermostats, which are situated in a particular house zone, and begin to function immediately after they receive a signal from the thermostats that heat is needed.
What is the purpose of zone valves on a boiler?
Explanation of Zone Valves on Heating Boilers - Controlling Hot Water Heat. The control of heating water through these different heating zones may be accomplished by use of zone valves (one per heating zone or area or loop of heating piping) which in turn are connected to individual thermostats.
What happens when the zone valve is open?
In all cases, when the zone valve is fully open, an end switch inside the valve tells the heating systems circulator to begin operating, causing hot water to flow through the zone.
How does a flair zone-a-Trol valve work?
Wiring details for the yellow Flair Zone-A-Trol valve shown above are given In all cases, when the zone valve is fully open, an end switch inside the valve tells the heating systems circulator to begin operating, causing hot water to flow through the zone.
Why is my zone valve not working?
If you dont get a voltage reading, there could be an internal wiring problem in the valve head, but its also possible the thermostat isnt closing, so you also have to test it. You should also test the transformer to make sure its actually sending 24-volt power to the thermostat before you blame the zone valve.
Can you replace a zone valve?
But before we get into the specifics of replacing a zone valve, we need to be familiar with the types of problems associated with zone valves. The great thing about hydronic heating systems is the ability to control the temperature in individual zones in your house.
What to do if your zone valve is stuck?
5 Simple Zone Valve Diagnostic Steps Mechanically-stuck zone valve motors. If your zone valve has a manual override lever you can test the valve to see if it will open and shut. A bad zone valve drive motor - the valve is not mechanically stuck but the zone motor wont operate the valve. Time for a new zone valve.
Can You troubleshoot the zone valve of a hydronic heating system?
You can troubleshoot the zone valve of a hydronic heating system. Honeywell zone valves offer the flexibility to regulate temperature in a home serviced by a hydronic heating system.
